If You Do So, How Has Journaling Helped Your Relationships?

Hi everyone! I'm new here, so forgive me if what I'm asking feels invasive or if there is a better sub for this. Feel free to only answer with what you're comfortable sharing.

I'm really really really early into my journaling career. I've been writing in a diary type-journal for the last four days, and I started my gratitude journal today. The reason I started was because I was having a lot of negative thoughts surrounding some of the relationships in my life, and I figured writing it out would help me work through the issues and better verbalize them with the people in question.

So, I'm asking this question because I wanted to know a couple things. Is it common to start journaling for these reasons? If you journal about your personal relationships, has it had a positive impact not only on you, but those relationships? And in addition to my diary and my gratitude journal, what other types of journaling helped you work through difficult relationships, if any?

Any answers are really appreciated. Thank you for sharing if you choose to do so.
